Follow this tutorial to build a Rotating Puzzle room for your Dungeon. This project incorporates parts from the OpenForge2.0 project with a few additional 3D-printed components and SparkFun's Qwiic and MicroMod systems to make a rotating puzzle room that can be activated by placing a magnet on the "secret" tile or remotely using a computer, phone, or tablet.
If you're feeling nostalgic for SparkFun's Autonomous Vehicle Competition, we might have something that will help. When Tawn Kramer's friends competed in the AVC and he couldn't make it, he wrote a simulator so that he could feel like a part of the action. The best part? It's open source and you can use it too!
